Abstract：Longitudinal crack is the most common quality defect on the surface of the beam blank. Based on small section beam blank of Masteel,The production data of 2019 were statistically analyzed, and the influences of the viscosity of protective slag, chemical composition of molten steel and protective casting on the surface longitudinal cracks of the billet were studied, which provided a reference for the production of high-quality shaped billets on the spot. The results show that high viscosity slag and clean molten steel are beneficial to reduce the surface crack of casting billet.
